Pelosi, Hillary and AOC do the same thing.

It's standard racist Democrat stumping.

Stumping and imitating the speaking patterns of audience groups is a form of linguistic convergence or audience design, where speakers (often politicians, performers, or influencers) adjust their accent, tone, vocabulary, and sentence structure to match the group they are addressing. This strategy is designed to create a sense of shared identity, foster social inclusion, or increase the perceived "social attractiveness" and authenticity of the speaker.

Pretty much ALL the Democrats do this, but what is way more telling is that they try to KEEP Blacks inferior. Just look how much they hate Black conservatives, it's not 5 seconds till they are saying uncle Tom, oreo or just straight up race traitor.
